i Specification of Letters Patent.

Patented Dec. 17, 1907'.

Application filed October l2. 1906. Serial No. 338.551.

To all whom 'it may concern:

Beit known that I, HYMAN COHEN, a subi ject of the Czar of Russia, andla citizen of the Russian-Empire, residing at New York, in the county ofNew 'York and State of New York, have invented certain new and usefulImprovements in Innersles, of which the following is a specification.

My invention relates to inner soles for boots and shoes andits noveltyconsists in the construction and adaptation of the parts vas will bemore fully hereinafter pointed out.

The purpose of the invention is to provide means for varying thethickness of the sole at 15`its heel and making such variations, eitheruniform across the entire width of the sole, or greater at one side ofthe sole than the other.

In the drawings, Figure 1 isa top plan view l of one of the two piecesof which the device is composed and a bottoni plan view of the otherpiece when the two are joined together;.

Fig. 2 is a plan view of the same, each piece being turned over g Fig. 31s a side elevation 25 of the parts shown in Fig. 2; 4 is a rearelevation of the device when the wedges are 'arranged at the same sideof the heel Fig. 5 is a similar view when the wedges are arranged at theopposite sides of the heel, and

Fig. 6 is a side view of the parts assembled as shown in Fig. 4.

In the drawings, 10 is the lower or positioning layer lof the lower heelpiece. It may be of cloth, leather, canvas, buckram or Its function isto carry, support and locate a lower wedge 11 made of soft elasticmaterial, such as soft rubber, and which wedge is preferably made in theform of a spherical or spheroidal seg- 40 ment with its wider edge 12coincident with the outer edge of a part of thelayer 10, and taperingclown to a thin edge at '13. This wedge is secured to the layer '10 byany suitable means, for instance, the rows of stitching 14. The wideredge ,12 is preferably beveled sloping toward the layer 10.

20 is the upper or positioning layer of the upper heel piece.. It may beof cloth,

leather, canvas, buckram, or other suitable material. 4 It is preferablymade of leather with a smooth upper surface, because it is the piecebrough-tinto contact with the foot support a cushioning layer 21 of feltor similar material secured by rows f stitches 22, or in any othersuitable manner, and to carry landlocate an upper wedge 23 made of softelastic material such as soft rubber. The wedge 23 is preferably made inthe forni of a spherical or spheroidal segment. Its wider edge 24 isbeveled and coincides in contour with the` outer edge of the layer 20.It diminishes inwardly to a thin edge25 andis secured by any suitablemeans between the layers v20 and 21.

The lower piece made'of the layer 10 and wedge 11 and the upper piecenia-dc of the layers 20 and 21 and the wedge aro connected to each otherby a short strip 30 ol' soft elastic material such as elastic webbing.

In using the device, if it is desired to increase the thickness of thesole at one side of the heel the parts are arranged as seen in rearelevation in Fig. 4 the upper 'and lower wedges being both on the saineside ol. the shoe and underneath each other. If, how ever, it is desiredmerely to increase the thickness of the sole uniformly the ,parts arearranged as shown in Fig. 5. In Fig. 4 the connecting strip 3() forms aflat hinge. In Fig. fthe strip 30 is twisted but 'forms a hinge which isnot in contact with the foot of the wearerjthe layers 20 and 21 beingbetween the wearer and the hinge. V

The lower heel piece 1s preferably made of less width than the upperheel piece, so that vthe entire device tapers downwardl)T and in wardlyand the upper layer of the upper piece .overlaps the layers beneath itso that their edges cannot come into contact with the foot of thewearer.

The device is very cheap to make and is convenient and efficient in use.

What I claim-as new is 1. A device of the kind. described, comprisingtwo hingedly connected ieces one of which consists of a positioningayer, a pro-` adapted to be arranged to position the thicker portion ofthe wedge of one over 'either the thicker `or thinner portion ofthewedge of the other.

2. A device of `the kind described, cornrising v'one piecev consistingvoi a positioning ayer, a protecting layer and a wedge, and anotherp1ece'consisting of a positioning layer and a wedge and united by aiiexible hinge .secured to both pieces at their rear. 1
